Bluetooth Communication Fault
The smartphone or tablet with DriveWizard Mobile
installed is too far from the keypad.
Use the smartphone or tablet 10 m (32.8 ft) or nearer to the keypad.
Note:
bCE
can occur when the smartphone or tablet is 10 m or nearer
to the keypad depending on the specifications of the smartphone
or tablet.
Radio waves from a different device are causing
interference with communications between the
smartphone or tablet and keypad.
Make sure that no device around the keypad uses the same radio
bandwidth (2400 MHz to 2480 MHz), and prevent radio
interference.
Note:
•
The drive detects this error when operating the drive with a smartphone or tablet using the Bluetooth LCD keypad.
•
Do a Fault Reset to clear the fault.
•
Set the stopping method for this fault in

•
Install a braking unit (CDBR-series).
•
Install a regenerative converter.
•
Increase the deceleration time.
You enabled the protective function for the braking
transistor when you have a regenerative converter.

The communications cable wiring is incorrect.
Correct wiring errors.
There is a short-circuit in the communications cable
or the communications cable is not connected.
•
Repair short circuits and connect cables.
•
Replace the defective communications cable.
Electrical interference caused a communication data
error.
•
Examine the control circuit lines, main circuit lines, and ground
wiring, and decrease the effects of electrical interference.
•
Make sure that a magnetic contactor is not the source of the
electrical interference, then use a Surge Protective Device if
necessary.
•
Use only the recommended cables or other shielded line. Ground
the shield on the controller side or the drive input power side.
•
Separate the communication wiring from drive power lines, and
install a noise filter to the input side of the power supply for
communication.
•
Decrease the effects of electrical interference from the controller.
The option is incorrectly installed to the drive.
Correctly install the option to the drive.
The option is damaged.
If the fault continues and the wiring is correct, replace the option.
Note:
•
The drive detects this error if the Run command or frequency reference is assigned to the option card.
•
Do a Fault Reset to clear the fault.
•
If the drive detects this error, the drive will operate the motor as specified by the stopping method set in
